# About

Nerdy Swede bitten, quite severely I might add, by the retro computing bug. Mostly into Commodore stuff, but old programmable calculators from the 70s also get my ***heart pumping***. And mechanical electromechanical calculators, *oh my gawd*. And old CRTs! **And stuff**.

The site name is an homage to the infamous [Halt and Catch Fire illegal opcode 0x9D](https://en.wikipedia.org/wiki/Halt_and_Catch_Fire_(computing)) of Motorola 6800 fame, as I have an extremely rare educational/development platform built by Ericsson for the physics department of Umeå University in the early 1980s that I'm planning on documenting and getting up and running.in progress

This site is self-hosted, so 100% uptime can't be promised. I'll try to have anything important uploaded elsewhere as well, such as archive.org or GitHub. [My typewriter font TT2026](https://tt2026.hex9d.com), based on [Fredrick Brennan's](https://en.wikipedia.org/wiki/Fredrick_Brennan) awesome [typewriter font TT2020](https://github.com/ctrlcctrlv/TT2020), is used throughout the site.

Reach out to me on my [Discord server amiga.device](https://discord.gg/C5WPUEJNXQ), on [Exxos forums](https://www.exxosforum.co.uk/forum/memberlist.php?mode=viewprofile&u=382) or [Bluesky (@kludge.tech)](http://bsky.app/profile/kludge.tech) if you want to yell at me.
